Safety questions
Is a natural supplement automatically safe?
No. Natural ingredients can cause side effects, interact with medicines or be unsuitable for some health conditions.
Can a supplement replace an erectile-dysfunction assessment?
No. Libido and erection function are different, and repeated erection problems can have treatable causes.
What symptom needs urgent hospital care?
A painful erection lasting around four hours is an emergency. Severe chest, neurological or testicular symptoms also need urgent care.
